Question

Answer 1

It depends on what the audio signal is.

Sound can have frequencies from 20 Hz to 20 kHz.  Most of it is between 200 Hz and 5 kHz, about.  And most sounds are mixtures of many different frequencies.

no, you can't calculate it, unless your stop watch can read thousanths of a second and your multimeter responds what fast. Which it doesn't.
